Detailed Solution

Concept- With the highest level of coalification, the highest level of energy and carbon content, and the fewest impurities, anthracite is the cleanest type of coal.
Anthracite is the finest type of coal available and contains about 95% carbon. In the sedimentary setting of deposition, the mineral matter composition of coal is originally determined. If the peat is frequently flooded by nearby rivers or distributary channels, a lot of mineral stuff from the running water has been deposited there. Pure coal would be coal with almost no trace amounts of minerals. There are some expectations, but anthracite is typically the coal that is thought to be the cleanest. Anthracite coal is the hardest and contains the most BTUs. On the basis of carbon content, it is frequently split into semi-anthracite, anthracite, and meta-anthracite. Then, coke is utilised as a high-carbon fuel for metal processing and other applications requiring a very fierce flame. Additionally, manufacturing uses coal. The gases, tars, and residues created when coal is heated can be applied to a variety of manufacturing procedures.
Carbon content in bituminous coal is lower (45–85%). The carbon concentration of lignite is only 25–35%.
Less than 60% of carbon is found in peat. Anthracite is therefore the purest form of coal.
Hence, option 2 is correct.
